What's going on with Jessica Simpson?

The singer, who has been the subject of a flurry of pregnancy rumors, stoked the flames even more Monday when she arrived at Los Angeles International Airport appearing as though she might be expecting.

Some Simpson observers say that pregnancy is the reason that in September she postponed her wedding to fiancé Eric Johnson, though others have said it's the singer's indecisiveness that has really held things up.

For her part, Simpson recently told People, "We're enjoying our commitment to each other. We want to take our time. … We might elope if it gets to that point."
